TL;DR: Experiments exploring the potential catalytic role of iron sulfide at 250°C and elevated pressures (50, 100, and 200 megapascals) revealed a facile, pressure-enhanced synthesis of organometallic phases formed through the reaction of alkyl thiols and carbon monoxide with IR sulfide as discussed by the authors.

TL;DR: In this paper, an Oregon andic soil was sequentially density fractionated at 1.65, 1.85, 2.28, and 2.55 cm −3 and analyzed the six fractions for measures of organic matter and mineral phase properties.

TL;DR: In this article, the authors used near edge X-ray absorption fine structure (NEXAFS) spectroscopy in combination with differential scanning calorimetry (DSC) and alkaline cupric oxide (CuO) oxidation to explore the assumption that chemical structure is a primary controller of decomposition.

TL;DR: In this paper, an Oregon andic soil at 1.65, 1.85, 2.28, and 2.55 g cm was sequentially density fractionated and the six fractions were analyzed for measures of organic matter and mineral phase properties.

TL;DR: In this article, the authors demonstrate a geochemically plausible scenario for chiral separation of amino acids by adsorption on mineral surfaces. And they demonstrate that calcite (CaCO(3)) when immersed in a racemic aspartic acid solution, display significant adsorization and chiral selectivity of d- and l-enantiomers on pairs of mirror-related crystal-growth surfaces.
